APPARATUS FOR DISCHARGING RE FUSE FROM SCOWS.

SPECIFICATION forming'part of Letters Patent No. 507,902, dated October31, 18%3. Application filed February 2,1893. fierial No. 460.673. (Nomodel.)

To all whom it may concern.-

Be it known that I, CHRISTOPHER GULL- MANN, a citizen of the UnitedStates, residing at New York, in the county and State of New York, haveinvented new and useful Improvements in Apparatus for Discharging Refusefrom Scows,-of which the following is a specification.

The object of this invention is an apparatus by means of which therefuse from scows can be removed to the dumping ground without thenecessity of dumping the refuse into the open water and removing it fromsuch open water to the dumping ground, a practice which involves thedanger, that a large portion of the refuse is caused to float on thewater and to be scattered in all directions.

The peculiar and novel construction of my apparatus is pointed out inthe following specification and claims and illustrated in theaccompanying drawings in which Figure 1, represents a plan or top view.Fig. 2, is a transverse vertical section in the plane 00 m Fig. 1. Fig.3, is a side elevation of the rotary crane and grapple on a larger scalethan the previous figures. Fig. 4, is a partial side elevation of thecrane and grapple on a still larger scale than the previous figures.Fig. 5, is a vertical section in the plane y y Fig. 4. Fig. 6, is ahorizontal section in the plane 2 2 Fig. 5. Fig. 7, is a side view ofthe grapple when closed. Fig. 8, is a back view of the same.

In the drawings the letterA designates my floating dock which consistsof a water tight compartment 10, 11, 12, a pump chamber 13 and an opencompartment 14 provided at its ends with doors 15. In the example shownin the drawings the water tight compartment consists of three sections10, 11, and'12, the sections 10 and 11 being located on one side and thesection 12 on the opposite side of the open compartment 14 and thesections 10, 11 are connected with the section 12 by strong timbers 16,16, or a single plank may be used which will form a continuous bottomfor the compartment 14. The pump compartment 13 is located between thesections 10 and 11 of the water tight compartment and it contains asuction and discharge apparatus 17 which serves to suck in the refusefrom the open compartment 14 through one or more suction pipes 18 andthen to force the same out on the dumping ground through the dischargepipe 19. Any suitable suction and discharge apparatus may be used but inthe example illustrated in the drawings, I have shown a drum which ischarged with steam from a boiler 20 (one or more) and then the steam iscondensed so as to create a partial vacuum in the drum and to producethe required suction, by which the refuse is drawn into the drum, andthen live steam is admitted to the drum by the pressure of which therefuse is forced out to the dumping ground. On the top of the pumpcompartment 13 is mounted a crane 21 which carries a scraper 22 and agrapple 23 and which is so c0nstructed that it can be swiveled round ona foot 24 to which it is connected by pins 25, so that it can be broughtto an inclined or vertical position, while the scraper and grapple canbe lowered to the position shown in full lines in Fig. 2 or raised tothe position shown in dotted lines in the same figure. The floating dockA is brought as close to the dumping ground as circumstances will allowand then the water tight compartment 10, 11, 12, is filled with water,so as to lower the dock in the water to a depth sufficient to permit thescows which carry the refuse, to be floated into the open compartment14. When a loaded scow arrives, it can readily be pushed through thedoors 15 each of which is susceptible of opening and closinghorizontally in both directions and when the scow has entered saidcompartment, the doors are closed behind so that any refuse which maydrop from the scow and, floats on the water, is prevented from beingfloated out of the compartment '14. If the scow carries a deck load ofrefuse,

such deck load may be removed by means of the grapple 23 and the swivelcrane 21, that is to say, when a quantity of the refuse has been graspedby the grapple, it can be raised up to the position shown in dottedlines in Fig. 2 and by turning the crane on its foot 24 the grapple canbe brought in such a position that the refuse, when released from thegrapple, will drop upon the dumping ground or upon a chute leading tosaid dumping ground. The refuse contained in the hold of the scow isdumped into the open compartment 14 and ICO removed from thiscompartment to the dumping ground by the combined action of the scraper22 and of the suction and discharge apparatus 17, said scraper-beingused to move the refuse up toward the suction pipe or pipes 18.

For the purpose of actuating the crane, the scraper and the grapple, Iemploy a steam engine 26 (Fig. 1) from which motion is imparted to ashaft 27 mounted in a frame 28in which are also mounted two drums 29,30. From the drum 29 extend the ropes 31, 32, under pulleys 33, 34,(Figs. 5 and 6) which are mounted on the pins 25 and from these pulleyssaid ropes 31, 32, extend over pulleys 35, 36, to sheaves 37 attached toa standard 38 which is firmly secured to the top of the pump compartment13, (Fig. 3.) From the sheaves 37 the ropes 31, 32, extend over pulleys39, 40 (Figs. 5 and 3) mounted in the crane 21, thence down to thegrapple 23 and their ends are fastened together and to the end of alever 41. This lever is pivoted to a link 42 which swings on a pivot 43secured in abracket connected to the head 44. of the scraper 22 (seeFigs. 3, 4, and 7). The grapple 23 is secured to a lever 45 which swingson a pivot 46 secured in the shank 48 of the head M and the tail end ofwhich is secured by a pivot 47 to the lever 41. The ropes 31 and 32 arewound in opposite directions upon the drum 29 (Fig. 1) and if this drumis turned so as to take up the rope 32 and let off the rope 31, thegrapple 23 is moved from its open position (Fig. 4) to its closedposition (Fig. 7) and if the drum 29 is turned in the oppositedirection, the grapple is opened. The shank 48 of the head 44 isconnected to the crane 21 by a pivot 49 (Figs. 3 and 4) and to saidshank is secured a slide 50 by means of a pivot 51 and this slideextends through a guide 52 which is pivotally secured to the crane 21(Fig. 3). In the guide 52 are mounted two pulleys 53, 54 and on theslide are secured two ropes 55, 56, (see Fig. 3.) The rope 55 extendsover the pulley 53 and under a pulley 57 to the drum 30 which is mountedin the frame 28 (Fig. 1) and the rope 56 extends over the pulley 54 andunder a pulley 58 to the drum 30 (see also Figs. 4 and 5). The ropes55,56, are wound in opposite directions upon the drum 30 and if thisdrum is turned so as to wind up the rope 55, the slide 50 is movedinward (Fig. 3) but when the drum 30 is turned so as to take up the rope56, the slide 50 is moved outward. By these means an oscillating motioncan beimparted to the scraper 22 and the head 4. 1 can be moved from theposition shown in full lines in Fig. 2 to that shown in dotted lines insaid figure.

The motion of the drums 29 and 30 can be controlled by a suitablereversing gear 61 such for instance as shown in Figs. 2 and 3, and inthe same manner the swivel movement of the crane is controlled by asuitable reversing gear 62 (Fig. 3).

What I claim as new, and desire to secure by Letters Patent, is-- 1. Afloating dock composed of a water tight chamber, a pump chamber and anopen compartment provided with doors, each of which opens and closeshorizontally in both directions, substantially as described.

2. A floating dock having a center open compartment 14 provided withopening and closing doors, water-tight compartments at opposite sides ofsaid center compartment, one of which water-tight compartments issubdivided into three sections, and a pump and suction and dischargeapparatus arranged in the center section and having its suction pipeextending into the center open compartment to remove the contents of ascow passed into said center compartment, substantially as described.

3. The combination with a floating dock composed of a Water tightcompartment, and an open compartment provided with opening and closingdoors through which a scow can pass, of a suction and dischargeapparatus having its suction pipe extending into the open compartment tocommunicate with a scoW passed thereinto, and mechanism for actuatingthe suction and discharge apparatus, substantially as described.

4. The combination with a floating dock composed of a water tightcompartment and an open compartment provided with doors, of a suctionand discharge apparatus, a scraper and mechanism for actuating saidsuction and discharge apparatus and scraper,substantially as described.

5. The combination with a floating dock composed of a water tightcompartment, and an open compartment provided with doors, of a swivelingcrane, a grapple, and mechanism for imparting to the crane and to thegrapple the requisite movements, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
